--- Comment #4 from Avi Kivity <avi@cloudius-systems.com> ---
According the dwarf 5 spec:

    If a Return Address register is defined in the virtual unwind table, and
its rule is
    undefined (for example, by DW_CFA_undefined), then there is no return
address
    and no call address, and the virtual unwind of stack activations is
complete.

So I think me code is correct (unless "Return Address" means somethign other
than rip).
